P LowsHARE.

SPECIFICATION forming part of Letters Patent No. 257,807, dated May 9,1882 Application filed December 13, 1881. (Model.)

To all whom t may concern Be it known that I, GYRUs YEisEn, otNewmanstown, in the State ofPennsylvauia, have invented certain new anduseful lmprovemen ts in Plows; and I do hereby declare that thefollowing is a full, clear, and exact description thereof', referencebeing had to the accompanyingdrawings, and to the letters of referencemarked thereon, whicll forni part of this specilo tication.

This invention relates to plows; and the nature of my invention consists'in a novel mode of constructing the share and the landside-bar, wherebythe share and bar are made [5 of separate pieces secured together, aswill be hereinafter explained.

1n the annexed drawings, Figure l is an elevation of the mold-board sideof the plow, showing part of a mold-board, the plow-beam, zo andlandsideplate applied to thel detachable landsidebar and share. Fig. 2is a perspective view of the landside-bar and its share together. Figs.3 and tare perspective views of the landside-bar and share detached.

The following description ot' my invention, when taken in connectionwith the annexed drawings, will enable others skilled in the art tounderstand it.

A designates the landside-bar, which terminates at one end in aplow-point, B, and which is formed with a recess, C, a horizon taloffset, D, and a vertical perforated ear, E, ar-

ranged on one side of the bar. The recess C is a narrow oblongdepression extending forward and downward, so that it is diagonal withrespect to the length ot' the bar A. The base of this recess extendsdeeper into the side of the bar than the upper extremity, as indicatedby dotted lines, Fig. 3. This inclined 4o recess C is at thejunction ofthe point B with the parallel sides ofthe bar, and in rear of the recessthe offset D is formed on the moldboard side of the bar. It is a horizontal table located a short distance below the top edge 4 5 of the bar A,and it has two holes', a a', vertically through it,one in rear of theother. In rear of the otfset D is the perforated ear E, whichrisesashort distance above the top edge of the bar, as clearly shown inv Fig.2.

The share G is formed with a horizontal ta- 5o ble or bed, b, which isprovided with vertical holes, which, when the share and table areadjusted in place against the side of the bar A, will exactly registerwith the holescta'through the offset D. The point ot' the share G has a55 tenon, c, formed on it, which,in size, shape, and inclination,corresponds to the recess O in the bar A. When the share is adjusted inits place to the bar the tenon cis received tightly in the recess C, andthe table b of the share is 6o solidly supported on the offset D, itsupper surface being iush with the top of the landside-bar. The share isthen rigidly secured to the bar A by means of a bolt and nuts d, and

a bolt and nuts, c, which latter bolt passes up i through theincid-board I and is rigidly secured to the beam H. The standard orlandside-plate is secured to the ear E and to the beam by means ofbolts. It will be seen that the share is rigidly secured to the bar A,and 7o that it can be easily detached from it for sharpening, or forsubstituting a new share in its place.

It is obvious that the bars may be adapted for right or left handshares. t Having thus fully described my invention, what I claim as new,and desire to secure by Letters Patent, is

l. The landside-bar'A, having the point B, the inclined recess C, theperforated offset D, 8o and the perforated ear, formed as described, andfor the purpose set forth.

2. The share G, having a perforated table, b, and a tenon, c, formed asdescribed, and for the purposes set forth.

3. The combination ot' the bar A, its point B, inclined recess C, andperforated offset D, with the share G, its perforated table b, tenon vc, and bolt-fastenings, substantially as described.

In testimony that I claim the foregoing as my own invention I affix mysignature in presence of two witnesses hereto.V

GYRUS YEISER.
